Quantum Mechanics - The structure and properties of electrons. Notes (slides 1-13)
Explanation videos 123 Frequency/Wavelength 9-1 Worksheet
1)To put your calculator in scientific notation mode click “2nd” then “DRG” Select “Sci” and hit “enter.” To put it back, select “FLO” 2) Put all answers in scientific notation if large or small. Round all answers to two decimal places. (3.34583 x 1014= 3.35 x 1014) 3) Show ALL work for each problem, and every number gets a unit.
Use the equation c=λf.
Calculate the following questions. If given wavelength, solve for frequency and visa versa.
Make sure all calculations for λ are done in m.
Don’t get confused by the units of frequency. You will see them as Hz, 1/s or . c = 3 x 108m/s.
Remember to use the E button on your calculator for scientific notation.3 x 108 Is the same as 3E8. 1) λ = 2.4 x 10-8m
2) f=1.5 x 1015Hz (remember that Hz means the same as 1/s)
